LOOM SHUTTLE-CHECK.

To all whom it may concern." 1 Be it known that I, JOHN 'B. CLoUTInn, acitizen. of the Dominion of Canada, residing at Saco, in the county ofYork and State of Maine, have invented certain new and use fulImprovements. in Loom Shuttle-Checks, of which the following is aspecification.

My invention relates to a 100m shuttle check, and the object of myinvention is to provide a shuttle check of improved con struction, andadapted to be combined with a stationary shuttle box of ordinaryconstruction, with which the ordinary. shuttle binder is used.

common stud, independent'of the binder pivotal stud, and adjustablerelative to each other, and located at the front. of the shuttle box,and near the outer end thereof. One

of the two levers has an engaging end ex tending in the path of theshuttle when it enters the shuttle box, to be engaged by the shuttleother of said levers has'an engaging end adapted to engage the's'hutt'erbinder, to yieldingly press the'binder against the shuttle when it is inthe box. There is an actuating spring intermediate the first mentionedlever, and in this instance an extension on the second mentioned lever,beyond the pivot point of said lever. mentioned lever has an extensionthereon be yond its pivot point, which is adapted to engage with anadjustingscrew carried on the second mentioned lever, and thefirstmentioned lever has an adjusting screw thereon, to regulate theinward movement of said lever, scribed.

I have shown in the drawing a stationary shuttle box at one end of theloom, with my improvements in shuttle check applied thereto.

1 Referring to the drawing:'-Figure 1 is a plan view of the right handend "of a lay of a loom, with a stationary shuttle box thereon, with myimprovements applied thereto; there is no shuttle in the box. Fig. 2corresponds to Fig. 1, but shows the parts shown in. Fig. 1, when ashuttle entersthe shuttle box; a shuttle is shown in this figure, and,Fig. 3 is a front view ofthe Specification of Letters Patent.Application filed .Ta'nuary'ilz, 1911.

as it enters the shuttle box, and, the

all as will be hereinafter de-- hub 13 shuttle Patented Octlff), 1911.Serial No. 602,138.

arts shown in Fig. 1, looking in the direction of arrow a, same figure.i i In the accompanying drawing, 1 ,is the right hand end of a lay'of a100m; carrying a stationary shuttle box or cell 2, for a shut tle 3, inthe usual way.

' 4'15 a rock shaft at the front of the lay, carrying the protectorfinger 5, which is adapted to bear at its upper end against the I innerend of the shuttle binder 6, which is pivoted at its outer end on a stud7 on the front side of the shuttle box. All of the above mentioned partsmay 4 be of the usual and well known construction. My shuttle checkconsists preferably of two levers or arms pivotally mounted on a I Iwill now describe my improvements.

The front side of the stationary shuttle box is provided in thisinstance with. a lug or projection 2 which has adjustably securedthereon a bolt 8. The bolt 8 has pivotally mounted thereon the-yokeshaped boss or hub 9, see Fig. 3, of an arm or lever 9, which extendstoward the outer end of the shuttle box. The free end of the armor lever9 is bent inwardly, and extends in this instance around the pivot stud'2'. of the shuttle binder 6, and is adapted to engage with its engagingend 9, which end is preferably covered with leather -1() or othersuitable material, the outer end of the shuttle 3, as shown in'Fig. 2,when the shuttle enters the shuttle box.

Ina downwardl extending'lug 9" on the arm 9 is an a justing screw 11,which turns in a threaded hole in said lug, and engages at its inner endthe lower part of the stationary shuttle box 2, and acts to limit theinward movement of the lever' 9. The lever .9. is provided with a boss2, thereon, see Fig.1, adapted to hold in a recessed portion a helicallycoiled expansion 'spring 12.

The second lever or arm 13 of my shuttle check has its hub 13 pivotallymounted .on the bolt 8. .Extending outwardly from the is'the extension13" having a boss 13' thereon, into which the expansion spring 12enters. The other extension 13, or main part of the lever 13, has theengaging end 13, adapted to engage with the binder 6, when the engagingend 9" of the lever 9 is moved outwardly when the shuttle enters the.shuttle box, in the direction indicated by the arrow in Fig. 1. On themain 105 part-.13 of the lever 13 is a boss 13, which art. When there isno .shuttlein the box,

the parts of the shuttle check mechanism will -normally be in theposition shown in Fig. 1.1 When the shuttle enters the shuttle box,in'the direction of the arrow,'Fig. 1,

the forward or outer end of the shuttle will come incontact with theengaging end 9 of the'lever 9, and inovesaid lever outwardly,and throughthe action of the exoftwo levers or arms having a common piv-- pa'nsionspring l2,"move the engaging end 13 on the port'ion13 of the lever '13yield-' ingly inwardly, to press against the binder 6, and force thebinder against the side of the shuttle, to bind. the same. It will beunderstood that the details of construction of my improvements may bevaried if desired.

. Having thus described my invention, what I 'claim as new, and desireto secure by Letters Patent is z- 1. In a 100m shuttle check,thecombination with the binder having a pivotal stud,

otal stud independent of the binder ivotal stud, and said levers beingadjustab e. rela tive to each other, and located at the front of theshuttle'box, one of said'levers extending in the path of the shuttlewhen it enters the box, to be engaged by the shuttle, and the J otherlever yieldingly pressed against the binder by the first mentionedlever, when the shuttle is in the box, to cause-the binder to pressagainst the shuttle.

2. In a loom shuttle check, the combination with the binder having apivotal stud,

- by thegfirst mentioned lever, when the shut-.

of two levers or arms having a common pivotal stud, independent of'thebinder pivotal stud, and locatedat the-front of the shuttle box,- andone of said levers extending in the path of the shuttle when itcntersthe box, to be engaged by the shuttle, andthe other lever yielding'lypressed aga nst the binder tle is in the box, to cause thebinder topress against the shuttle.

" 3'. In' a loom shuttle check, the combination with the binder having apivotal stud,

of two levers or arms, having a common pivotal stud, independent of thebinder pivotal stud, said leverslocated at the front of theshuttle'box,and onset said levers hav:

other of said levers having one arm with an engaging end to engage thebinder, and carrymg an ad ust1ng stud, to enga c said extension on thefirst mentioned ever, and

having a second arm on the opposite side of its fulcrum, and anactuating spring intermediate said second mentioned arm and the firstmentioned lever, for the pur )ose stated.

4. In a loom shuttle check mechanism, the combination with the protectorrod carrying the protector finger, and said finger to engage a shuttlebinder, and said shuttle binder, of a shuttle check, comprising twoseparate levers, pivotally mounted, and having tl1e same fulcrum, one ofsaid levers havinga curved arm extending around the fillcrumofthebinder, with 1ts engaging end in the path of the shuttle when it entersthe shuttle box, and having an extension on the opposite side ofitsfulcrum, and theother lever havin an arm with an engaging end toengage t- 1e binder, and carrying an ad- -justing screw to engage saidextension on the first mentioned lever, and a, secondarm on the oppositeside of its fulcrum, and a helically coiled expansion springintermediate said second arm and'the first mentioned lever, for thepurpose stated.

,- 5. In a loom shuttle check mechanism, the combination withthe'pro'tector rod carrying 'the'protector finger, and said finger, toen gage a shuttle binder,- and said shuttle binder, of a shuttle checkcomprisingtwo separate levers, pivotally mounted, and having the samefulcrum, one of said levers having a curved arm extending around thefulcrum of the binder, with its engaging end in the path of the shuttleas it enters the shuttle box, and having an extension on the oppositeside of its fulcrum, and carrying an adjusting screw' to limit theinward movement of said lever, and the other lever havingan arm with anengaging-end to engage the binder, and carrying an adjusting screw toengage said extension on the first mentioned lever, and a second arm onthe opposite side of its fulcrum, and a helically coiled expansionspring intermediate said second arm and the first mentioned lever, forthe'purpose stated.
